SSR MARKERS IN GENETIC DIVERSITY ASSESSMENT OF CROP VARIETAL COLLECTIONS: MOLECULAR BASES AND PRACTICAL APPLICATIONS
Simple Sequence Repeat (SSR) markers – tandem repeats of 1–6 nucleotide motifs – exhibit high polymorphism generated by replication slippage and unequal crossing-over, with mutation rates of 10⁻⁴–10⁻² per locus per generation. The multi-allelic nature and codominant inheritance of SSR loci provide exceptional discrimin...
